LELink Bluetooth Low Energy BLE OBD-II OBD2 Car Diagnostic Tool for iPhone/iPod/iPad and Android. New: Configurable Auto On/Off

This worked exactly as advertised. For what the dealer said couldn't be done, we got done for $40. This and SpyLeaf to fix the door lock settings on my 23 Leaf. There was some issues with setup, I had to turn on the bluetooth on the app on the iPhone settings, which Tech support helped be with. They were very responsive to support the app that connected with their product. I am still waiting for the app folks to help me, but it won't be needed because of the fast and expert advice given by the hardware guys. Depending on your vehicle and software, you could control door locks, beepers, lights, and other timers, without the expense of the dealer. As well as studying your engine codes, battery health and the like. Great product.

I've been using this for nine months so far, and it works great!I use this on an iPhone. You do need to purchase software for this, but it should work with many OBD2 apps. I use OBD Fusion ($10), and it works nicely, letting you customize your app dashboard, read and clear codes, etc. This app has a fast-response mode, which drains your phone battery faster, but gives you even faster than the standard speed. (Standard is probably one update per second.) This device has no problem keeping up.This device is low-profile, and of course doesn't have any wires to plug in -- you just plug in the device itself, and it gets power from the OBD2 port. (All cars in the U.S. since I think 1996 have to have standard OBD2 ports.)I use this on a 1996 Lincoln Mark VIII and a 2001 Jeep Grand Cherokee. No problems switching between vehicles.My only disappointment is that I was hoping there was a power switch, or that it would automatically shut off after shutting off the car, so I could leave it plugged in without draining the battery. But it stays on the whole time -- you can't connect when the key isn't in the "run" position, but it still gets at least enough power to keep flashing the LEDs. I've accidentally left it plugged in a couple times, and it's not enough draw to kill the battery overnight, but I still wouldn't want to leave it plugged in all the time. (Obviously, this was not a big enough problem for me to lower my rating.)Oh, and speaking of the LEDs, they're easy to see when you're looking at the device, but they're not distracting for me when driving, because the OBD2 ports on both my vehicles are under the dash, so you can't see the lights at all when driving, even in your peripheral vision. I suspect most cars are like that, but if you can directly see your OBD2 port when driving, you might end up putting electrical tape or something over this to hide the lights.

I recently purchased a 2020 Nissan Leaf Plus and I hesitated to purchase this dongle to use with Leaf Spy Pro. Well I’m so glad that I did purchase this dongle. I’ve used it well over a dozen times and it works perfectly. Every time I connect it and open Leaf Spy Pro it just works. I even plugged it into my old Toyota with a check engine light on and it worked again flawlessly.The Nissan Leaf is a wonderful first/budget EV with 2 issues. The first is a ChadeMo connector instead of a newer standard CCS. The bigger more serious issue is the lack of active thermal battery management. After reviewing options I opened the hatch that covers the main battery disconnect in the back seat floorboard. I put a Noctua industrial pc fan with 3,000 rpm’s and I had it sit on the opening. I went out and watched the battery temp via Leaf Spy Pro. Results after 45 minutes of driving and a little being parked and idle outside temp 90 degrees in South Georgia. This plan worked very well it kept the temp of the battery at least 12 degrees cooler than outside temperature. I did run the AC and it did cut down my miles per kWH. However achieving a little over 10 degrees under outside temp is a win.I hope this helps. Please don’t hesitate to purchase this product as it works great.

Works as expected; no issues.

Works great on my Nissan leaf spy. But unable to use on other obd2 code reading

Just plug in used for a 1019 LEAF installed LEAF Spy

I could get it to connect to my iPhone 16 Pro, but it won't return any data from the car. This was the recommended one to use with LeafSpy, but it's junk. Returning to Amazon.

I had bought a cheaper black Friencity Bluetooth OBD2 diagnostic interface from Amazon and had nothing but trouble trying to make it connect to my phone or to my car. I decided to spend a few more dollars and get a better one that was mentioned in a YouTube video. Plugged it in and it worked connecting to my phone immediately. Big plus. I like the fact that it has a clear cover and is small, so no matter which way the USB 2 port on your car faces you can see the lights working. On the previous one I returned, the lights were turned away from me, facing the brake pedal so I had to use my phone's camera to even see if it was turned on. I would highly recommend this product. I had absolutely no problems with it on a Nissan Leaf running Leaf spy.
